The commissioning and matching of the
control unit to local conditions and build-
ing characteristics, as well as instructing
the user in the operation of the system,
must be carried out by your heating con-
tractor.
As the user of new combustion equip-
ment, you may be obliged to notify your
local flue gas inspector of the installation
[check local regulations]. Your local flue
gas inspector will also inform you [where
appropriate] about work he may be
required to perform on your combustion
equipment (e.g. regular checks, clean-
ing).
Your system is preset at the factory
The control unit is factory-set to "Heat-
ing and DHW".
Your heating system is therefore ready
for use:
Central heating
■ Between 6:00 and 22:00 h, the rooms
are heated with 20 °C "Set room
temp" (standard heating mode).
■ Between 22:00 and 6:00 h, the rooms
are heated with 3 °C "Set reduced
room temp" (reduced heating mode,
frost protection).
■ Your heating contractor can make fur-
ther settings for you during commis-
sioning.
You can change any settings individu-
ally at any time to suit your require-
ments (see chapter "Central heating").
DHW heating
■ Between 5:30 and 22:00 h, the DHW
is heated to 50 °C "Set DHW temper-
ature". Any installed DHW circulation
pump is ON.
■ Between 22:00 and 05:30 h, the DHW
cylinder temperature will not be rehea-
ted. Any installed DHW circulation
pump is OFF.
■ Your heating contractor can make fur-
ther settings for you during commis-
sioning.
You can change any settings individu-
ally at any time to suit your require-
ments (see chapter "DHW heating").
Frost protection
■ Your boiler and DHW cylinder are pro-
tected against frost.
Wintertime/summertime changeover
■ This changeover is automatic.
Time and date
■ The day and time were set by your
heating contractor during commission-
ing.

Power failure
■ All data is saved if there is a power
failure.
Terminology
To provide you with a better understand-
ing of the functions of your control unit,
the appendix contains the chapter "Ter-
minology" (see page 44).
Tips on saving energy
Utilise the setting options for the control
unit and remote control (if installed):
■ Never overheat your rooms. Every
degree by which the room temperature
is reduced saves up to 6 % on heating
costs.
Never set your room temperature
higher than 20 °C (see page 18).
■ Never set the DHW temperature too
high (see page 25).
■ Only activate the DHW circulation
pump for times when DHW is drawn
off. Set the time program for this (see
page 27).
■ Select the heating program that meets
your current requirements:
– For short absences (e.g. shopping
trips), select "Economy mode"
(see page 23).
As long as economy mode is activa-
ted, the room temperature is
reduced.
– If you are going away, set the "Hol-
iday program" (see page 23).
As long as the holiday program is
activated, the room temperature is
reduced and DHW heating is off.
– In summer, when you don't want to
heat any rooms but do need DHW,
select the heating program "Only
DHW" (see page 25).

In conjunction with a solar ther-
mal system:
DHW heating is set at the factory to
start at 05:30 h. On sunny days, the
DHW cylinder receives sufficient
heat from the solar thermal system
that the DHW temperature is still
high enough the next morning. You
can program DHW heating to start at
10:00 h, for example.
– If you don't want to heat the rooms
and you don't require DHW for an
extended period, select the heating
program "Standby mode" (see
page 16).
For additional energy saving functions of
the control unit, please contact your
heating contractor.
Further recommendations:
■ Correct ventilation/airing.
Briefly open windows fully and at the
same time close the thermostatic radi-
ator valves.
■ Close roller shutters (if installed) at
dusk.
■ Set thermostatic valves correctly.
■ Never cover radiators or thermostatic
valves.
■ Controlled DHW consumption: A
shower generally uses less energy
than a full bath.

You can change any settings on your
heating system centrally at the program-
ming unit of the control unit.
If remote control units are installed in
your rooms, you can also adjust the set-
tings at the remote control units.

tions
